I just got a 05 BEW with 310,000 km that I just got running and driving put a new SMF and clutch in and drove around a bit and the car ran beautifully. Pulled the valve cover to check the cam and the lobes look brand new no edges or worn down lobes. Couple days pass and I fire the car up to warm it and a odd ticking sound started to come from the timing belt/cylinder 1 area I thought a cam bearing was shot so I pulled the valve cover again and re inspected the cam and lifters, everything checked out good but the tick (witch almost sounds like a squeak when it warms up) is still their. So at this point I'm thinking timing pulley or tensioner witch I should be checking this week. Any input on what this tick is will be very much appreciated.

Check the alternator clutch pulley. First pull the serpentine belt off and start it and see if the sound is still there. If so, you've narrowed it down to likely timing components.
If the alternator clutch pulley siezed up, it'll make a squeaky tick sound. They're not that hard to replace, especially with the bew, as it's easy to pull the alternator and swap the pulley.
Also check the tensioner pulley and the power steering pump.

I definitely wouldn't risk running it, especially if it is possibly timing belt pulleys. I had an idler lock up (only had 40k miles on it!) And it started to tear the belt. Currently I've got a car at the shop that the tensioner locked up and took the engine out. Not worth risking it.

Most of us will simply replace the timing belt kit when we buy used. Unless you're confident it's been done and done correctly.
